level of Chlorophyll- a (say 20 mg/m 3 ); the minimum of the two allowable loadings can then be taken as
the carrying capacity (Fig. 8.49(b)).
Fig. 8.49 Water quality model for determination of carrying capacity: (a) organic loads, flushing times and key water
quality indicators at six FCZs; (b) allowable organic loading dictated by DO and algal biomass limits (PLDO—potential
lowest dissolved oxygen)
